Overview
Built to meet modern gas utility demands, our Intelligent Diaphragm Gas Meter integrates signal acquisition, data transmission and temperature & pressure sensing within a single device. It enables remote meter reading, valve control and real-time fault alarms, supporting both pre-payment and post-payment billing models for flexible project rollout.
Available in G1.6, G2.5 and G4 variants, the meter achieves accurate metering with built-in temperature and pressure compensation. Equipped with an IP65-rated steel enclosure and a battery lifespan exceeding 10 years, it supports NB-IoT, 4G, LoRaWAN and NFC communication. Additional capabilities include tiered pricing schemes, remote balance recharge, and automatic alerts for abnormal operating status.
